Re-examining the 'More People Less Erosion' Hypothesis:\ud Special Case of Wider Trend?

Recent research into natural resource rehabilitation based on in-depth case studies has highlighted situations where population growth and agricultural intensification have been accompanied by improved rather than deteriorating soil and water resources(e.g. Tiffen et al., 1994). Drawing on new case studies in six countries (Burkina Faso, Ghana, Nigeria, Senegal, Tanzania and Uganda), this paper examines how widespread are the prospects for positive outcomes of the ‘more people, less erosion’ type

Analysis of interference to remote passive microwave sensors

The final acts of the 1979 World Administrative Radio Conference (WARC) were analyzed to determine potential interference to remote passive microwave sensors. Using interferer populations determined from the U.S. Government and FCC Master File Lists and assuming uniform geographical distribution of interferers, the level of interference from shared services and active services in adjacent and subharmonic bands was calculated for each of the 22 passive sensing bands. In addition, due to the theoretically large antennas required for passive sensing, an analysis was performed to determine if smaller antennas, i.e., relaxed resolution requirements, would have an effect on interference and to what extent

Remote sensing frequency sharing studies, tasks 1, 2, 5, and 6

The following tasks are discussed: adjacent and harmonic band analysis; analysis of impact of sensor resolution on interference; development of performance criteria, interference criteria, sharing criteria, and coordination criteria; and spectrum engineering for NASA microwave sensor projects

VSX J003909.7+611233: a new slowly pulsating B (SPB) star in Cassiopeia?

We report the discovery of a new 13th magnitude variable star in Cassiopeia close to the variable KP Cas.Analysis of six days of intensive photometry shows a regular, near sinusoidal modulation with an amplitude of 0.024 mag and a period of 0.43815(31)d.Although its colour indicates a spectral type around F0 the star probably suffers up to 2−2.5 magnitudes of extinction, so could be an Aor B-type star. Given the period, the low amplitude, the shape of the lightcurve and the probable spectral type we consider it most likely to be a slowly pulsating B-type (SPB) star.The variable has been registered in the International Variable Star Index with the identifier VSX J003909.7+611233

Is Islam Pro- or Anti-Environmental? Interpretations and Implications

Religion has, throughout the centuries, been a powerful institution on the macro level, yet also stands as a force having significant influence in people’s personal lives. This does, however, lead to questions of how a traditional institution such as religion may or may not be adequate to address problems of the Late Industrial Era, most notably the environmental crisis. In this paper, we inquire how various dimensions of Islamic literature and thought can contribute to preserving the natural environment. We find that concepts such as “dominion of men over the earth” and “specialness of humankind” can lead to anti-environmental interpretations of Islam. Nevertheless, other interpretations of Islamic teachings emerge that are compatible with environmental stewardship. However, a number of Islamic governments have shown a decided bias against environmental stewardship, particularly in cases where there is an authoritarian government and one placing an emphasis on economic “development”. In counterpoint, Islamic Mysticism, or Sufism, can provide a spiritual context for environmentally conscious action

Elective Affinities in the Anthropocene: Christianity and the Natural Environment Reconsidered

To reach a deeper understanding of the complex relationship between religion and the natural environment, it is important to move beyond essentializing any religious tradition as having a pro-environmental or anti-environmental ethic. Rather, prior work has shown that the canonical, scholarly, and popular literatures and discourse of a number of religious traditions can and have been socially and rhetorically constructed as supporting an array of positions, from preservation to profligacy, and much in between those two ideal types. In this paper, we develop Max Weber’s theory of “elective affinities” and adapt it to the Anthropocene, to make the case that in a fragmented society, people and communities of convenience tend to choose the tropes and framing from the dominant culture to justify self-interested action. That often can take the form of religious discourse. In the sense of finding a wide array of practical interpretations relative to the environment, the theory is largely supported, although we do find important nuances. It is instructive to look at how the language and legitimacy of one institution (e.g. religion) has been used to justify and legitimate that of others (e.g. the polity). While these processes of institutional co-optation can be effective in the short run, they may have corrosive longer-term effects. Key rhetorical, and in fact political, battles in the Third Millennium, will likely be organized around how to adapt pre-industrial religion to late industrial and perhaps post-industrial times, and it remains to see how central the natural environment will be in what communities hold sacred

Improving Loss Estimation for Woodframe Buildings. Volume 2: Appendices

This report documents Tasks 4.1 and 4.5 of the CUREE-Caltech Woodframe Project. It presents a theoretical and empirical methodology for creating probabilistic relationships between seismic shaking severity and physical damage and loss for buildings in general, and for woodframe buildings in particular. The methodology, called assembly-based vulnerability (ABV), is illustrated for 19 specific woodframe buildings of varying ages, sizes, configuration, quality of construction, and retrofit and redesign conditions. The study employs variations on four basic floorplans, called index buildings. These include a small house and a large house, a townhouse and an apartment building. The resulting seismic vulnerability functions give the probability distribution of repair cost as a function of instrumental ground-motion severity. These vulnerability functions are useful by themselves, and are also transformed to seismic fragility functions compatible with the HAZUS software. The methods and data employed here use well-accepted structural engineering techniques, laboratory test data and computer programs produced by Element 1 of the CUREE-Caltech Woodframe Project, other recently published research, and standard construction cost-estimating methods. While based on such well established principles, this report represents a substantially new contribution to the field of earthquake loss estimation. Its methodology is notable in that it calculates detailed structural response using nonlinear time-history structural analysis as opposed to the simplifying assumptions required by nonlinear pushover methods. It models physical damage at the level of individual building assemblies such as individual windows, segments of wall, etc., for which detailed laboratory testing is available, as opposed to two or three broad component categories that cannot be directly tested. And it explicitly models uncertainty in ground motion, structural response, component damageability, and contractor costs. Consequently, a very detailed, verifiable, probabilistic picture of physical performance and repair cost is produced, capable of informing a variety of decisions regarding seismic retrofit, code development, code enforcement, performance-based design for above-code applications, and insurance practices
